Specification of Letters Patent. Patented J111yv26, 1910.

Applicationled November 6, 1909. Serial No.` 526,639.

"To all whom it may concern:

ingy rece tacles and cars, and the principal p object o the invention is the provision of a car truck provided with a tilting body or receptacle, so mounted as to allow it to be removed, and whose bottom consists of two 2i hinged parts, having novel means whereby these parts may be raised or lowered, and when raised or in a closed osition, the same are securely locked, and when lowered, they are disposed at angles so as to guide the plastic material or concrete into forms.

The means for raising and lowering the partsI of the receptacles bottom comprise a U-shaped lever extending from end'to end of the receptacle, and pivoted thereto and provided w1th curved ends, to which itmen are connected which are connecte with links of saidV parts, and when the said `U.l

v shaped lever is thrown in a horizontal position, thus closing said parts forming the bottom, the said pitmen are disposed upon a dead center, thereby securely holding the pieces forming` the bottom of the receptacle' in a closed, position.

A further object of the invention is the provision of triangular frames at either end of the car track, between which the receptacle or car body is suspended, and in such a manner as to allow the receptacle' or car body tobetilted to either side, whereby the `contents of the rece tacle may be dumped.V

Another object o the invention is to` so Weight lthe U-shaped lever that the Weight of the hinged parts of the bottom is overcome, so that the said parts may be returned to their closed positions after dumping the contents of the receptacle. 4

Another object'is the rovision of means fr'permittingthe links etween the pitmen and the parts of the bottom to separate'ap proximately central of thereceptacle or carl body. It is to b e understood that after the U'shaped lever passes the dead fcenter, the two parts forming the bottom of the recep# tacle are automatically opened, because of the weight ofthe contents thereon, which is in excess' or'V theweight of the U-shaped lever. L

Another object is the provision of a catch upon the side of the receptacle with which the U-shaped lever engages, to prevent the same from being accidentally raised.

A further object is to provide the receptacle or car body with means to which a suitable hoisting cable maylbe attached, in order to elevate the receptacle or car body from the car truck. The elevating of the car bodyl or receptacle is employed when there is "excavating being` conducted, in

which work suitable cranes, derricks or similar devices are employed, whereby' the receptacle or car body may be lifted or elevated from, the car truck and lowered into the excavation to be lilled, and then returned to the truck.

In this specification and the' annexed drawings, a particularV design of device is adhered to, but the'invention is not to4 be conned to this specific form. The device in its actual reduction to practice may necessitate changes and variations; the right thereto belongs to the applicant, provided such changes and variations are comprehended by the appended claims.

With the above objects in view, the invention consists of further combinations of parts and detailed structures, which will be hereinafter described, shown in the Adrawings and pointed out in the appended claims y Iny the drawings z-#Figure 1 is a perspective view of a `car truck having the dumpn receptacle mounted thereon and provide with the two-part hinged bottom. Fig. 2 is a transverse sectional view, showing the parts formingthe bottom closed. Fig. 3 is a transverse sectional view through the receptacle and the car truck, showin the bottom open'. Fig. 4 is an end'elevation showing thereceptacle' tilted to one side in full lines and to theopposite side in dotted lines, in which case the bottom of the receptacle is'clesed, and Fig. 5 is a detail perspective view of ther'eceptacle removed from the car truck, and having attached thereto a suit-4 ablehoisting'l cable, clearly showing that the which are hinged at 5 and so arranged as to allow them to extend vwithin a form, when opened, so as to guide concrete or other plastic materialthereinto.

Pivoted at each end of the car body or receptacle are the end pieces 6 of the U-shaped lever 7, which end pieces are provided with 'curved portions 8. Pivoted to the extremi- ,ties of these curved portions are pitmen 9,

tothe lower ends of which the links- 10 are pivotally connected. The lower ends of the links, there being four in number, two at each end, are pivotally connected to the ends at 11 of the two parts forming the bottom, as shown in Figs. 1, 2 and 3 of the drawings.

When the U-shaped lever is thrown in the inclined position, as -shown clearly in Figs. 1, 2 and 5, the pivotal connections of the pitmen to Athe curved ortions and to the links are disposed slight y to one sideiof the pivot l2 of said end pieces 6, thus holding the parts of the bottom securely in their closed positions.

To open the parts forming the bottom, the

U-shaped lever'is raised, and when the pivotal connections of the itmen to the curved portions and the said ginks pass the dead center, the weight of the material within the body ork receptacle will cause the parts forming, the bottom to readily open, in the positions as shown in Fig. 3.

To cause .the links connecting the free portions of the hinged parts of the bottom and the lower extremities of the pitmenvto sep# arate approximately central y of the car body or receptacle lugs 12*1 project laterally Afrom the car bo and between the said links. `It will be c early evident that as the parts of the bottom are lowered, the said links will be separated by these lugs.

When the U-sh'aped lever is in the position as shown in Figs. 1, 2 and 5, the same engages, a catch or lug 13, secured to the side of the receptacle or car body, by means of screws'or other suitable means 14.

In the drawings, a car truck 15 is shown,-

secured to the triangular frames or supports and the frame of the truck by screws or other suitable means 21.

Projecting from either side of the triangular-shaped frames or supports are bracket members 22, which form suitable bearings 23, in whichfthe lugs 24 of the receptacle or car body are journaled. These lugs or projections of the receptacle or car body are integrally formed upon plates 25 which are secured to each end of the car body or receptacle by screws or other means. 26. In this manner, the receptacle or car body is prop- 1n a horizontal or a tilted position. When it is desired to tilt the receptacle or car body,

one side or the other of the rece tacle is raised so as to oscillate the receptac e or car body upon two of the said lugs or projections, suliicient to allow the contents of the receptacle to be emptied.

Extendin across the receptacle from end to end is a ail member 27, the parts 28 of which are angularly arranged with relation to one another; These parts 28 are securely connected and braced with relation to the ends of the car body or receptacle by means of the angular plates 29. These angular plates embrace opposite sides of the parts 28 and are secured to them and to the ends of the car body by means of screws, bolts or 'other fastening devices 30.

iece 6 of arm 6,

between which and the lever a spring 6b is connected, which holds the arm 6 in an operative or inoperative position, as hereinafter explained. The arm 6a is provided with a roller 6c which is adapted to engage an inclined projection 6c1 which will raise the lever 7 upwardly beyond dead center, when the contentsof the car or cars will be auto matically dumped. When the arm 6l is in an inoperative position, as shown in dotted lines in Fig. 1, the spring 7 b holds it in place, which spring extends about the corner of the car, as shown in dotted lines. But, however this sprin always remains on the side of the pivot o the arm 6a adjacent the corner of the car, the angles of the lever 7,

the end piece 6 thereof and the corner of the be oscillated or tilted to one side or the other upon said lugs.

3.
